VAPOR-BURNER.

SPECIFICATION forming part of Letters Patent No. 295,315, dated March 18,1884.

' Application led January 25, 1883.

.To all whom it may concern,.-

Bc it known that we, J. BENNETT WALLACE and GARsoN MYERS, citizens of the United States, residing at Chicago, in the county of Cook, in the State' of Illinois, have invented certain new and useful Improvements in Va por-Burners, which are fully set forth in the following specification, reference being had to the accompanying drawings, in which- Fignre 1 is a front elevation of a vaporburner having our improvements. Fig. 2 is the head of the oil-pipe) and the seat O of the a rear elevation of the same, the handle of the needle-valve being broken away, and the cap of the burner being in section. Fig. 3 is a bottom plan view of 'the baseplate of the burner and the parts included in the saine casting. Fig. 4 is a top plan view of the same. Fig. 5 is a top plan view of the mixing-tube and the conducting-shield. Fig. 6 is a rear elevation ofthe same. Fig. 7 is avert-ical longitudinal section,-showing the needle-valve, the adjoining part of the vaporizing-tube, and the drip-cup.

The same letters denote the saine parts in u all the iigures.

Our invention relates to apparatus for the development and combustion of hydrocarbon vapor for heating purposes, and more particularly to apparatus of the general construction shown in the patent of Zebulon Davis, No. 237,826, issued February l5, 1881; and it consists in the several devices and combinations of devices, which will be fully set forth hereinafter, and deinitehT pointed out in the claims, the object be'ing to enhance economy of the construction and promptness and certaint-y of operation.

In the drawings, A denotes the base-plate of the burner, and A the perforated cup.

We cast the head B of the main oil-pipe B oi the vaporizing-tube C (which leads from needlevalve G all in one piece. As here shown, they are of the same piece, with the baseplate ofthe burner. That part of the vaporizing-tube which is between the margin of the base-plate and the needle-valve seat is cast straight, and after being drilled, to form a passage for the liquid or vapor, is bent downward in a uniform curve, as shown in Figs. 1, 2, and 7. W'e are thus enabled to avoid the use of (Model.)

one screw-plug, and, by a slight wrenching of the lower part of the tube, to restore the alignment of the jet-ori1ice c with the mixing-tube D, should it ever be accidentally set awry-a correction which is impracticable with the conformation shown in the patent referred to, but very easy with that now shown.

The screw-plug E, which closes the lower end of the Vnporizingtube, extends far enough below it to form a support for the drip-cup E,

and is preferablyintegral therewith, asshown in Fig. 7. The plug may, however, be passed up through a hole in the bottom of the cup, so that the cup rests on the enlargement e, and the two then welded together. By thus inaking the plug to support the cup, an appreciable economy in manufacture is effected.

The mixing-tube D is a separately-formed curved tube, whose upper end passes through a central circular hole in the base-platcof the burner, just large enough to allow the tube to turnwithin it. An annular collar, d, is formed on the tube, the upper surface of which collar is smooth, so as to turn readily against the lower surface ofthe base-plate. A washer or thimble, D', screwed or otherwise' fastened on the tube D above the base-plate, and having a smooth under surface in contact with the plate, (io-operates with the collar d to hold the tube in place. The baseplate is preferably thickened around the central aperture, so as to give abetter bearing for the tube to turn in.

The deflecting-shield F (whose oce is to direct a diminished current ofgas or a dame to the undersurface ofthe hase-plate and the adjacent part of the vap orizing-tu be, and th us keep the burner hot while the gas is shut off from its interior) is in our construction affixed to one side of the mixingtube, so as to turn with it. A perforated ear, f, projecting backward from the shield F, admits a lug, cl', projecting laterally from the mixing-tube, to pass through it, which, being headed down upon the ear, holds theshield in place. By this means a single motion turns the mixing-tube out of line with the gas-jet and brings the shield into line with it.

The edge of the collar d is provided with a notch, d2, within which projects a stop, a., formed on the lower surface of the base-plate A, for the purpose of properly limiting the rotary movement of the tube D in bringing the roo said tube` or the shield into or out of line, as just described. Said tube and shield are turned by the handle D2, projecting from the mixing-tube on the side opposite that to which the shield is attached.

The shield F is preferably made tubular in its upper part; or it may, if desired, be tubular throughout its length, as shown.

The device which We have described for turning the iniXing-tube and the conductingshield together is considerably more economical than the former construction, by which the shield is provided with a separate pivotal bearing, on which it turns in front of the mixing-tube; and the operation of changing the direction of the gas-current is shorter and more certain, the range of shifting being equal only to the distance from the axis of the mixingtube to that of the shield. Moreover, the mouth of the mixing-tube can, in the construction set forth, be brought as near to the jetoriflce as may be found desirable, since it is unnecessary to leave room for the shield between them.

What We claim as our invention, and desire to secure by Letters Patent, is

l. In avapor-burner, the combination, with the base-plate and laterally-arranged needlevalve, of a bent mixing-tube having its upright portion mounted to rotate in the baseplate, whereby its lower and laterally-projecting part may be swung horizontally into and out of line with the needle-Valve, substantially as described.

2. In avapor-burner, the combination, with the base-plate and laterally-arranged needlevalve, of a bent mixing-tube having its upright portion mounted to rotate in the baseplate, audits laterally-projecting lower portion provided with an external detlectingshield, substantially as described.

3. rlhe combination of the base-plate A, provided with a circular aperture, the mixingtube D, iitted to rotate therein, and the Washer D', applied to the tube above the base-plate, 45

substantially as and for the purpose set forth.
